Antilock Brake System Abs Model Based Design Computer Science Essay

Antilock Brake System Abs Model Based Design Computer Science Essay An Antilock Brake System (ABS) is a closed loop control system that modulates the brake torque that is applied to the wheel in order to prevent the controlled wheel from becoming fully locked. ABS is among the most important safety systems in a vehicle. In automatic highway system, automatic brake actuation is a very important part of the overall vehicle control system. It prevents the wheel lock-up under critical braking conditions, such as those encountered with wet or slippery road surfaces and driver panic reaction (Bosch, 1995). By preventing the wheel lock-up, ABS ensures that the vehicle remains responsive to steering wheel inputs. Reduced stopping distance on account of ABS is more evident on wet or slippery road surfaces (Garrick et al., 1998). 1.2 MODEL BASED DESIGN Designers of embedded control system software face difficult challenges. In addition to the need to complete projects at low cost and within tight schedules, embedded control system software designers must prov ide predictable performance and competitive features for the products they deliver. Traditional methods of designing, testing, and implementing embedded control systems cause designers to wait until late in the design effort, when actual or prototype products and real-time embedded targets become available, to find out if software really works as it was intended to. Only then, as system integration occurs, can the designer uncover the errors that may have found their way into the product during the early design stages. Model-Based Design with MathWorks tools provides a proven technique for creating embedded control systems. It is used today for satellites, aircraft, and many other aerospace applications, in the automotive industry, and for process control, computer peripherals and industrial machinery. Through Model-Based Design, embedded control system design teams can begin evaluating software designs without using prototype products and real-time targets. The MathWorks environmen t for Model-Based Design allows engineers to mathematically model the behavior of the physical system, design the software and model its behavior, and then simulate the entire system model to accurately predict and optimize performance. The system model becomes a specification from which you can automatically generate real-time software for testing, prototyping, and embedded implementation, thus avoiding manual effort and reducing the potential for errors. Fig 1.1. Model-Based Design for embedded control system software Changes or corrections to the system requirements and specifications are easily incorporated into the model, fully evaluated by simulation, and automatically reflected in the final real-time embedded software. 1.3. MODELING AND SIMULATION To effectively design an embedded control system and accurately predict its performance, designers must understand the behavior of the entire system in which the control system will reside. MATLAB and Simulink form the core environm ent for Model-Based Design for creating accurate, mathematical models of physical system behavior. The graphical, block-diagram paradigm of the MathWorks environment lets you drag-and-drop predefined modeling elements, connect them together, and create models of dynamic systems. These dynamic systems can be continuous-time, multi-rate discrete-time, or virtually any combination of the three. You can create custom model elements or reuse legacy code-based models by incorporating C, Fortran, or Ada code directly into the modeling environment.

Strategic Management and Strategic Competitiveness Essay - 3

Strategic Management and Strategic Competitiveness - Essay Example Internet and telecommunications infrastructure are the major contributors of globalization as people from different can easily connect and interact. This global interconnection increases job opportunities, ideas and competitiveness in equal measure. In its expansion process, Disney targeted those countries whereby people were greatly aware of the company and the services it offered. Another strategic consideration was the stability of the economy and the disposable income, which the citizens of that country used on leisure. Trade policies, political and microeconomics stability also played a huge role in determining whether Disney opened a branch in that country. Globalization has led to the increase of the companies’ market and this has forced it to open many branches to cater for the high demand of its services. The company has opened up branches in UK, Spain, Italy, France, Japan and US. This new branches have led to the increase of the total revenue generated. In 2004, the company made a gross income of $2.5 billion (Krasniewicz & Disney, 2010). The emergence of new technology has led to the introduction of video editing software and 3D, which has led to the efficient production of the films. Global recession negatively affected the company. The Disney parks and resorts would suffer during winter as the rate of people going there reduced significantly. This led to the falling of its revenue resulting in a financial crisis. The company has been forced to increase its entrance ticket fee to counter with the reduced number of visitors. Industrial organization and resource based model impact on above-average returns The corporation needs to come up with measure that would help it get returns, which are above average. This would help ensure that it is not operating at a loss and that it can be able to sustain its operations. The resource-based model deals with how the corporation could use its internal resources to its advantage and avoid extra costs (Mon tgomery, 1995). The resources include the capital invested, the corporation’s workers, brand name and the patents. Once the corporation has identified its resources, the next step to take is to compare it with its competitors. This would help in identifying the area that the corporation is lagging behind and needs to improve on. The study would also help enable the company identify its unique resources as this gave them a competitive edge over their competitors. This competitive edge would make them reduce certain costs and thus maintain above average returns. The industrial organization approach is the examining of the relation of the boundary of the firm and the market it is operating on. It is hard to examine the market by mere observation and the corporation creates a situation that is similar to a perfect competition market. This makes the firm operate on limited information and assumes that there are many barriers hindering entry into the market. This would make the fir m gather information about the market as new entrant and in the process of doing this it identifies the measures it can take to enter the market. The research helps the firm identify its strengths and weaknesses and in the process, it can avoid overhead costs and losses. This overview is

Growth strategies Essay Example | Topics and Well Written Essays - 250 words

Growth strategies - Essay Example The product development strategy involves developing existing products or introducing new lines of products in order to increase the firm’s revenues. The market development strategy involves creating new markets for the company such as penetrating new geographical regions (Gaebler, 2010). Multinational corporations often utilize market development strategies. A diversification strategy makes sense when good opportunities can be found outside the present business (Kotler, 2003). Tenet Healthcare Corporation is a healthcare delivery system founded in 2003. It is one of the nation’s largest healthcare providers with 49 acute care hospitals in 11 states, 64 outpatient centers, 3.88 million outpatient visits (Tenethealth, 2009). The firm generated in 2009 over $9 billion in revenues. The company current has a presence in 22% of the United States region. The company recently made a strategic move to achieve growth. The growth strategy the company utilized was the market devel opment strategy. The company reached an agreement with Keystone Mercy Health Plan which covers Hahmemann University and St. Christopher Hospital for Children in Philadelphia (Tenethealth, 2011). I believe that the approach utilized by the company to achieve growth was the right decision. The firm was able to successfully penetrate the Philadelphia marketplace without investing resources.

The Strategic Growth Plan for an SME Essay Example | Topics and Well Written Essays - 4250 words

The Strategic Growth Plan for an SME - Essay Example At that time nobody appeared to be interested in the product. But today Microsoft Vista is widely reviewed and talked about even before its formal launch. lacked a degree of functionality and achieved little popularity. Coke started off in 1886 when in May 1886 Dr. John Pemberton a pharmacist from Atlanta, Georgia started selling for five cents a glass. The first year of operation ended with the figures of $50 worth of sales Vs the production cost of $70 i.e. a net loss of $20. Today Coca-Cola Company is the world's leading manufacturer, marketer and distributor of nonalcoholic beverage concentrates and syrups. Infosys Technologies, a global consulting and IT services company was founded with some borrowed money by it founder Narayana Murthy. But today it is managing the IT needs of world's who's who in the business field. Small and Medium Enterprises is therefore the beginning of a giant stride for business strategists and determined entrepreneurs. SMEs need to improve their business skills to help them survive and grow. What is required to make an SME a competing and a big company is a vision and a strategic growth plan implemented with grit and determination by the owners/ managers. A strong SME sector contributes to a flexible and buoyant economy, creating jobs, providing the foundations for the large companies of the future and contributing to the nation's long term growth and international competitiveness. Firms can grow by interacting with key local players including universities, customers and research centres (Asheim & Isaksen, 1997). The main barriers to growth for smaller firms arise in the form of financing, organization and competition from new products or companies. A strategic growth plan calls for managing all such eventualities. SME Sector As far as IT sector is concerned China and India are in the forefront of global turnaround in IT enabling services and business process outsourcing. Both these countries have taken major share of the outsourcing revenue from the developed nation. Since initiating economic reforms and open policy in late 1970s, China has achieved tremendous success in economic development. The economy has changed from a centrally planned system to a more market-oriented one with a rapidly growing private sector. China now is the fastest growing economy in the world, with GDP expanding at an annual average rate of around nine percent over the past two decades. China has started recognizing the potential of SMEs and visible efforts are there to prove the point. For example, China organized its first SME fair in October 2004. Despite the progress in privatization, a considerable part of China's economy remains controlled by large State Owned Enterprises (SOEs), many of which are termed as inefficient and unprofitable. This slow march towards opening up of economy has prevented the inflow of IT led outsourcing into China to a certain extent. Major beneficiaries of the outsourcing boom are the Small and Medium Enterprise (SMEs), that effectively means less growth potential for SME sector. India on the other hand has proved to be a grooming ground for SME sector. With the exodus of IT companies from Europe, America and other parts of the world towards India, the burgeoning Business Process Outsourcing (BPO) sector promises to be a growth

Observation of Teaching English Focusing on Teacher-Student as well as Essay

Observation of Teaching English Focusing on Teacher-Student as well as Student-Student Interactions - Essay Example The projector was on but was never used for the duration of the class. Likewise, some students were deemed absent, as observed from the greater number of vacant seats as compared to the first observation period. He talks in a monosyllabic manner that is perceived to be monotonous and students at the back would strain to hear the entirety of his discussion. The students posed diverse stances ranging from perceptive, partially responsive as a class, partially attentive (which means there were a few who were really inattentive), somewhat indifferent, and generally unparticipative. Description of Teacher-Student Interactions The professor discussed the day’s subject matter on the need to examine the context of the sentence by enumerating a point-by-point sentence structure as detailed in their course material. He tried to solicit participation from the student by asking them questions after relevant points from the course material were presented. Apparently, only one student from Saudi Arabia was virtually responding actively to his inquiries. The rest of the students (predominantly Asian) were either very softly responding in their respective seats or silently observing and listening during the whole discussion. At one point where handouts were needed to be disseminated, Saudi students voluntarily stood up and assisted in distributing the materials to the other members of the class. As noted, other students (Asian) were not at all participating and one actually saw two students changing seats upon the start of the class discussion; and where one student even changed seats twice for some reason. Even worse, some Asian students were also seen sleeping in class (a total of three students) and neither the professor nor the classmates made any efforts to wake them up. The professor either did not see them or was indifferent to students sleeping in his class. Description of Student-Student Interactions Regarding observing student-student interactions, one could d educe that the students are already well acquainted with each other. This acquaintance was observed to have negative effects in terms of exhibiting private conversations and communications with each other, without regard to the professor discussing the lessons. These were actually three (3) Asian students talking to each other while the professor was explaining the lesson in front of the class. A positive student interaction was observed as two (2) Saudi students voluntarily assisted the professor in distributing the handouts. The rest of the classroom environment was predominantly silent during the lecture due to absence of reaction and response; as well as active participation from the students. Description of Lesson, Activities and Group Work The lesson was delivered purely using a lecture approach. Only the course materials were the sole reference for the discussion. Despite availability and access to using the overhead projector, it was not at all utilized. Likewise, the soft v oice, monotonous manner of speech and communication pattern, as well as being stationary (standing in front of the class) limited movement, activity, vitality, and diversity in instructional approach and use of instructional materials. At some point in time, about 30 minutes after the start of the

Voluntary assumption of liability Essay Example | Topics and Well Written Essays - 2500 words

Voluntary assumption of liability - Essay Example Nonetheless, such acts fail the English legal system’s interpretation of what constitutes justice, fairness and equity, in contracts. Edwards, Edwards, and Wells (2011) argued that an application of a ‘genuine’ assumption of liability as the premise upon which extra-contractual risks are based can repair the damages resulting from the injustice. Sykes (2012) pointed out that this effectively circumvents the legal challenges arising from the wider interpretation of a binding contract.The second legal hurdle relates to the fairly wide confines within which a binding contract falls (Gruidl, 2008). In Tort, however, Best and Barnes (2007) averred that numerous limitations face the English judicial system. For instance, time constraints in the acquisition of claims, narrowly explained vicarious liability, and the amount of damages may hinder the handling of claims in a fair manner, especially claims stemming from direct business between two parties in cases where a bin ding contract cannot be implied. In such situations, the generous provisions guiding the establishment of contracts do not apply (Horrigan, 2012).Lastly, a party may use the idea of assumption of liability to claim liability for issues that were part of a contract (Sykes, 2012).   In fact, the doctrine of assumption of responsibility was introduced into English law to settle extra-contractual liability arising from â€Å"non-intentional† injury other than physical injury to any individual party. These include; psychological injury, economic damages and nervous shock.... Lastly, a party may use the idea of assumption of liability to claim liability for issues that were part of a contract (Sykes, 2012). In fact, the doctrine of assumption of responsibility was introduced into English law to settle extra-contractual liability arising from â€Å"non-intentional† injury other than physical injury to any individual party. These include; psychological injury, economic damages and nervous shock (Edwards, Edwards, and Wells, 2011; Horrigan, 2012). Difficulty in compensation Best and Barnes (2007) suggested that these kinds of injury are hard to remedy. In effect, the defendant and the wider society would find it hard to withstand the losses. But, the researchers added that a blanket refusal of liability is unacceptable. Therefore, English law was created to provide grounds for a new platform for the application of logical, narrow responsibility in tort, for such damages. Harpwood (2008) contend that such provisions of English law seek means of narrowi ng the application of responsibility in negligence which, hitherto would only be proved by foreseeable injury. In English legal system the concept of assumption of liability is today clearly employed separately within the province the Duty of Care in Negligence (Horrigan, 2012). Additionally, the idea is slowly being outmoded by the three-fold-test under the Duty of Care, and the slow evolution of the key facets of the common law, which focus on expanding liability. Rights of Third Parties Act 1999 Gruidl (2008) noted the significance of the Rights of Third Parties Act 1999, which expanded the infamous narrow understanding of contract and the liabilities that may arise thereof under English law. The new legislation repealed the

Becoming an Actor Essay Example for Free

Becoming an Actor Essay There are many people who dream of being an actor/actress and hope to make it into Hollywood someday. While acting may seem easy, it takes a lot of hard work and dedication. It isnt until you are on stage in front of a large crowd that you may realize how tough it really is.
